sArnrY-Locx.

To all whom it may concern:

. Be it known that I, GRovnR E. a citizen of the United States and Stateof Michigan, tain new and useful Safety-Locks, of which the accompanying drawings.

This invention relates to a safety lock for,

automobiles, power boats or the like and more especially to means for ting off the fuel supply from the engine and at the same time holding the ignition c1rcuit open so that the motor to which the device is applied cannot be operated except:

by the holder of a they for the lock proper. The device is also applicable to electrically propelled vehicles lfor holding the motor circuit open.

'Theinvention consists in the matters hereinafter set forth, and more particularly pointed out in the appendedclaims.

In the drawings, Figure 1 is a view, partially in front elevation and partially in section, with the outer casing removed, of a device that-embodies features of the invenis a view, partially in side elevation and partially in section, of a. device with the fuel valve omitted; and Fi 3 is 111-111 of i 1.

As herein shown in preferred form, a use plate 1 of suitable material and design, forms a support at its lower end for a bracket plate 2 havin a split lug 3 or the like for gripping and olding a tubular extension 4. The lowerend of the latter is screwthreaded or otherwise secured in a casing 5 of a valve adapted to be introduced into the supply pipe of a fuel system for a motor towhich the device is applied.

In preferred form the valve has an annular seat '6 on which a closure 7 ma rest, closure being a apted to seal aniaperture through, a diaphragm 9 clamped in the upper part of the casing by the inserted tube 4 when the closure is raised from the seat 6. A stem 10 of the closure extends freely through the diaphragm opening and the tube and: has a guide collar 11 on the upper portion thereof,

passing through longitudinal slots in the bar. The end portion of the bar adjacent the bracket plate 2 is upturned to form a. lug 1 1 through which theupper p0rtion of the stem 10 passes. A spring 15 that encircles the stem in compression between the collar 11 and the lug 14.- yieldingly moves the stem as the latch bar 12 isoscillated.

; Or the stem is otherwise suitably connected to the latch bar to be yieldingly moved thereby. A. spring finger or other like means indicated at 16 engages a pin 17 on the bar to normally hold the latter in initial poslti'on with the valve closure '1 away from.

may he manually its seat. The plate 12 moved to close the valve 5 by a finger lever 18 of appropriate design pivoted on the base and provided with a bell crank arm 19 bearmg against the upper end of the bar 12 to force the latter into closed position when the finger is moved in onedir'ection and to clear the bar when posite way.

A look 20 of appropriate design is secured against the face of the base 1 over the upper portion of the bar 12 with the latch bar 21 of the lock adapted to be normally promotion of an outturned ear 22 of the bar 12. The latter is so disposed that .when the latch bar is retracted by the spring 16 the ear lies in the path of outward movement of the lock latch 21 while when the projected by proper manipulation o the lever 18, as in Fig. 1, the latch of the lock, which is preferably spring projected, snaps past the ear 22 and. prevents its return.

The upper end portion of the stem 10 car ries an electric contact fingr 23 which in this instance is shown as a spring arm clamped between nuts 25 on the stem. This terminal may be grounded, as herein indicated, to the base and consequently in sethe ignition cir; suit of the motor or it may be insulated with terminal portion 27 of the circuit limb is secured by a binding post 28 or the like, and spring finger 29 arranged the finger is swung in the oplate is limb. The otherjected laterally therefrom into the: path of too parts are so disposed as to leave the fuel valve open. The casing 30 incloses the entire mechanism, being removably secured on the base plate 1.

irl g the lock the latch bar is released ger lever depresses the latch bar to close the valve, the latch of the lock sna-ppin past the lug on the latch bar and holding t e lat ter in projected position. The spring connection between the valve stem proper and the latch bar yieldingly forces the valve clo sure to properly seat so that there is no leaka e. By inserting the key and manipulatand at once retracted by its spring finger. At the same time the circuit which has been broken by the outward movement of the latch bar is again closed.

As a result of this construction a device is obtained which effectively holds the fuel supply of the motor to which it is applied, cut oil if desired and which also breaks the ignition circuit of the motor. \Vith the parts disposed and arranged as shown it is impossible to tamper with the mechanism to allow the opening of the valveor the closing of the circuit. The device is applicable to electrically propelled vehicles by omitting the fuel valve, and placing the electric cutout devices in the motor circuit of the car.

Obviously, changes in the details of construction may be made without departing from the spirit of the invention, and I do not care to limit myself to any particular form or arrangement of parts,
